Title: sql: support computation directly on sqlalchemy tables

I started deprecating the `SQL` object in favor of just `sqlalchemy.Table` objects. Then I realized that lots of `into` stuff will have to be rerouted. Punting on this until after the `into` refactor. Little bit done. Will merge soon if no comments.
